What are TWICE support advertisements? (Quick Reference Table for 9 Members' Birthdays)

| MOMO | November 9 | Japan |

Checking JYP Entertainment's Guidelines
TWICE is a group belonging to JYP Entertainment. Before putting out a support advertisement, it's basic etiquette to adhere to the following points:
- Avoid unauthorized use of official images/videos: Do not directly use cuts from official music videos or magazine photoshoots. Use fan art or authorized materials.
- Do not include slanderous or disparaging expressions towards other members: The main principle is to stick to celebratory messages.
- Include contact information: Depending on the media, it may be mandatory to include the advertiser's group name and email address.
Oshi-Ad also provides support for checking agency guidelines during the application process.
Popular Media and Costs for ONCE (TWICE Fans)
Digital Signage (from approx. 30,000 yen)
Oshi-Ad's main media type. Applications can be made as little as one week in advance, and individuals can easily place advertisements. Advertisements can be displayed in high-traffic areas such as Shibuya, Shinjuku, Osaka, and Umeda.
Outdoor Vision / Large Street Monitors (from approx. 100,000 yen)
Display on large screens in entertainment districts. This has a strong impact, and displaying it on the birthday itself adds a special touch. Sharing costs among multiple ONCE members through crowdfunding is also a popular option.

Mobile advertisements that drive around concert venues and event locations. Displaying these in conjunction with TWICE concerts directly reaches fans who are present at the venue.
